Abstract

Colonne de distillation à cloches à bulles d'entretien facile, pour distillation de liquides encrassants et/ou à forts dépôts Colonne de distillation caractérisée en ce que les structures de cloches à bulles peuvent être démontées et retirées de la colonne, et en ce que les surfaces intérieures des cloches à bulles et les surfaces intérieures et extérieures des collets de cloches à bulles, surfaces les plus critiques pour l'encrassement de la colonne, sont recouvertes d'un revêtement de polytétrafluoroéthylène ou d'une substance analogue. L'invention s'applique aux cloches à bulles pour liquides encrassants et/ou à forts dépôts.Easy-to-maintain bubble-bell distillation column for distillation of fouling liquids and / or strong deposits Distillation column characterized in that the bubble-bell structures can be dismantled and removed from the column, and that the inner surfaces of bubble bells and inner and outer surfaces of bubble bells collars, the most critical surfaces for column fouling, are coated with a coating of polytetrafluoroethylene or the like. The invention applies to bubble bells for fouling liquids and / or with strong deposits.
